UN 1008 Boron trifluoride, liquefied under pressure ADN 2025 (Shortinfo)

Neutron radiation detectors containing non-pressurized boron trifluoride gas may be carried under this entry provided that the following conditions are met: (a) Each radiation detector shall meet the following conditions. (i) The pressure in each detector shall not exceed 105 kPa absolute at 20°C; (ii) The amount of gas shall not exceed 13 g per detector; (iii) Each detector shall be manufactured under a registered quality assurance programme; NOTE: ISO 9001 may be used for this purpose. (iv) Each neutron radiation detector shall be of welded metal construction with brazed metal to ceramic feed through assemblies. These detectors shall have a minimum burst pressure of 1800 kPa as demonstrated by design type qualification testing; and (v) Each detector shall be tested to a 1 x 10EXP(-10) cm³/s leaktightness standard before filling. (b) Radiation detectors carried as individual components shall be carried as follows: (i) Detectors shall be packed in a sealed intermediate plastics liner with sufficient absorbent or adsorbent material to absorb or adsorb the entire gas contents; (ii) They shall be packed in strong outer packaging. The completed package shall be capable of withstanding a 1.8 m drop test without leakage of gas contents from detectors; (iii) The total amount of gas from all detectors per outer packaging shall not exceed 52 g. (c) Completed neutron radiation detection systems containing detectors meeting the conditions of paragraph (a) shall be carried as follows: (i) The detectors shall be contained in a strong sealed outer casing; (ii) The casing shall contain sufficient absorbent or adsorbent material to absorb or adsorb the entire gas contents; (iii) The completed systems shall be packed in strong outer packagings capable of withstanding a 1.8 m drop test without leakage unless a system's outer casing affords equivalent protection. Packing instruction P200 of 4.1.4.1 of ADR is not applicable. The transport document shall include the following statement "Transport in accordance with special provision 373". Neutron radiation detectors containing not more than 1 g of boron trifluoride, including those with solder glass joints, are not subject to ADN provided they meet the requirements in paragraph (a) and are packed in accordance with paragraph (b). Radiation detection systems containing such detectors are not subject to ADN provided they are packed in accordance with paragraph (c).

For each member of the crew, a pair of protective goggles, a pair of protective gloves, a protective suit and a suitable pair of protective shoes (or protective boots, if necessary). On bord tank vessels, protective boots are required in all cases.

A suitable escape device for each person on bord.

A toximeter appropriate for the current and previous cargo, with the accessories and instructions *1) for its use. __________ *1) The instructions could be kept on board electronically in a human-readable format.

A breathing apparatus ambient air-dependent.

Holds containing these substances shall be ventilated whith the ventilators operating at full power, where after measurement it has been established that the holds are not free from toxic gases and vapours given off by the cargo. The measurement shall be carried out immediately after loading. A control measurement shall be repeated after one hour. The results of the measurement shall be recorded in writing. Alternatively, on vessels only containing these substances in containers in open holds, the holds containing such containers may be ventilated with the ventilation operating at full power only when it is suspected that the holds are not free of toxic gases and vapours given off by the cargo. Prior to unloading, the unloader shall be informed about this suspicion.
